Abstract: An auto-darkening filter of a welding shield has a brightness-sensing unit, an optical shutter and a processor. The brightness-sensing unit generates a first signal or a second signal. In a high-sensitivity mode, the processor controls the optical shutter to operate in a dark state or a bright state depending on intensity of the first signal being higher or lower than a threshold value. In a low-sensitivity mode, the processor controls the optical shutter to operate in the bright state when intensity of the second signal is lower than the threshold value, and automatically change to the high-sensitivity mode from the low-sensitivity mode when intensity of the second signal is higher than the threshold value.

Abstract: A method to measure and report electromagnetic radiation power includes receiving electromagnetic radiation and generating an electrical signal having a magnitude based on the power of the electromagnetic radiation. An adjustable gain may be applied to the electrical signal to generate an amplified electrical signal that may be sampled to generate a digital sample. The adjustable gain may be controlled based on the value of the digital sample and the digital sample may be associated with a gain value. One or more calibration factors may be selected based on the gain value associated with the digital sample and the selected calibration factor(s) may be used to calculate the power of the electromagnetic radiation.

Abstract: A solar blind corona camera designed specifically for use on 60 Hz or 50 Hz AC power distribution equipment is based on the fact that electrical discharge corona only occurs above some voltage threshold level on the positive and negative voltage peaks of the AC power waveform. Between these peaks, when the AC voltage is below the discharge corona voltage threshold, the electrical discharge and resulting corona are extinguished. An image sensor is used to both capture the corona-plus-ambient light image during the corona period and the ambient light image during the non-corona period. The ambient light image is then subtracted from the corona-plus-ambient light image leaving only the corona light image which is annunciated and displayed along with the ambient light image. This process effectively renders the corona camera solar blind so it can be used both at night and during daylight.

Abstract: In embodiments of object presence and condition detection, a light is emitted that is directed at a first edge of a translucent object to pass through the translucent object, such as a lens. An intensity of the light is detected proximate an opposing, second edge of the translucent object. A presence and/or a condition of the translucent object can then be determined based on the detected intensity of the light that passes through the object. The translucent object can be implemented as a multi-lens array, and a laser light is directed through optic surfaces of the multi-lens array with a laser. The presence and the condition of the multi-lens array can be continuously determined as a safety compliance of the laser light being directed through the multi-lens array.
